Transportbånd med forbedret fastgörelse mellem stang og led

摘要

A conveyor belt with rods and connective links that engage one another so as to resist lateral deflection and rotational movement about the rods during conveyor operation. The links are mechanically affixed on the rods and the rod is resistance welded to the link apertures. In addition to the resistance weld, the rods include diametrically enlarged protrusions or swells that are placed proximate the link apertures to constrain the links from lateral movement on the rod. At the ends of the rod, the protrusions are in the form of an upset or button head. An alternative embodiment comprises rods having a larger diameter through most of their length, and reduced diameter portions at their ends where they are attached to the connective links. The larger diameter allows for the construction of wider conveying surfaces. Further alternative embodiments include rotational constraints of the links relative to the rod. The additional fixation steps such as manual welding used in conventional belt manufacture are thus eliminated. By fixing the links and rods together in the manner disclosed, repeated movements of the link legs relative to the rods are eliminated thereby significantly reducing the chances of fatigue failure of the links.
